Summary
Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease, which results in the death of nerves that innervate muscle, known as motor neurons. Recent studies using mouse ALS models showed that certain cells that normally support motor neurons may be directly contributing to their death in ALS. We propose to derive ALS-diseased human cells and investigate how these cells may react in ‘normal’ tissue. These studies are clinically relevant in understanding ALS pathological processes.

Summary
Mitochondria are the powerhouses of cells. They generate energy from the food we eat and air we breathe. However, excess nutrients can cause mitochondrial stress and damage that lead to disease. The objective of this research is to understand how the brain regulates mitochondrial stress responses throughout the body. Therefore, this project will identify stress-response processes that are directly relevant to health and disease.
I am a developmental neurobiologist interested in finding out how neurons in the brain are assembled and wired together. I am also interested in finding a cure for patients who have brain damage from trauma or stroke by preventing damaged neurons from dea
Context Is Everything – Understanding How Spatial, Temporal And Behavioural Context Affect Sensory Processing

Summary
A possum in a tree is cute to see on a bushwalk, but scary to hear when we are trying to sleep. This illustrates that how we perceive a “target” is affected by “modulators” that are close in space or time to the target, or by the task at hand. Deficits in contextual modulation are apparent in many neurological conditions. This project will investigate the neural circuitry that mediates spatial, temporal and task-related contextual modulation.
My research focuses on understanding pathobiological mechanisms in acute and chronic neurodegenerative conditions such as stroke and Parkinson’s disease which have large burdens on the community through health care costs and on families because of the lack of effective treatments. An improved understanding of how brain cells die and of how the most abundant brain cell, the astrocyte, can be engineered to be a resource for regenerative medicine offer promise for improved clinical management.
Hereditary Motor Neuronopathies And Neuropathies: Mechanisms Of Neurodegeneration And Potential Modification.

Summary
The aim of the study is to investigate the pathophysiology of motor neuron degeneration in its various acquired and inherited forms. Nerve function will be determined by clinical and neurophysiological assessments in patients. The findings of the study will reveal further insights into the cause and progression of disorders of the motor neuron. This data may function to monitor disease progression, response to potential therapies and lead to the development of further therapeutic strategies.
What drives the pain associated with inflammation is unknown as is the relationship between pain and the extent of tissue damage associated with disease, for example, arthritis. Our laboratory has shown that a particular protein is a key mediator of inflammatory pain. The project is to understand how this particular protein promotes pain, including how it sensitzes neurons.
